CAN-CRIMPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,917, dated June 25, 1889.

Application filedApril 5, 1889. Serial No. 306,056. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER SLAYS- MAN, J r., a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Can-Crimping Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to can-crimping machines, and has for its object certain improvements in construction which will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a front elevation of my improved machine; Fig. 2, a plan view, on an enlarged scale, of one of the crimping-heads detached; Fig. 3,

a side view of the same; Fig. l, a vertical section of a can before the head has been erimped; and 5, a similar view of a can after crimping, with the flare of the flange ex- 5 aggerated.

Reference being had to the drawings and the letters thereon, A indicates the frame of the machine, which is adapted to be secured to a work bench or table in a factory. The

0 frame is provided with pedestals or bearings B B at one end, having removable caps a (z, and in said bearings is supported a shaft 0, which is provided with a pulley D between the bearings B B, a crimping-head E, and a grooved collar E, which engages with the bifurcated upper end of a lever G for moving the shaft and crimping-head longitudinally for the purpose of inserting and removing a can H to be operated upon. The lever G is secured to the frame A at Z), and to a treadle I by a link or rod 0 for throwing the head E into engagement with a can, and is provided with a spring (Z for throwing the head out of engagement with a can. A ball e may take the place of the treadle for holding the head to its work while crimping. On the opposite end of the frame A are pedestals or bearings K K, having movable caps f f, and in said bearings is supported a shaft provided with a pulley L between the bearings K K and the crimping-head M, which has no longitudinal movement in the bearings. The pulleys D and L are driven from any power-shaft by a belt, (not shown,) and run in opposite directions, as indicated by arrows, to cause the heads E and M to operate upon opposite ends of a can and secure the can against revolving. The crimping-heads are provided with a recess N to receive one end of a can, and four arms g, in which are supported crimpingwheels h, of the form shown in Fig. 3, and each provided with a shaft 1, which is supported transversely in the arms g of the head. Upon each end of the shaft 2' of the Wheel h rests a coiled spring 7c, confined in pockets Z in the armsby screw-threaded plugs m, which also regulate the tension of the springsiupon the wheels h, and as a consequence regulate the pressure of the wheels upon the can. The shafts i are free to reciprocate in their elon- 7 gated bearings n. (Shown in Fig. 2.)

In theapplication of the crimping-wheels h to the head or bottom 0 of a can, the groove p in the wheels forms the bead q, (shown in Fig. 5,) and the surface 1' on the wheels flares the flanges on the head or bottom out, as at s, and forms a receptacle for solder, while the body of the can is also flared out into the concavity formed by the bead g. In applying the solder to the can it flows between the flange of the head or bottom into the can and forms a perfectly tight joint.

Having thus fully described my invention, what I claim is- 1. Ina can-crimping machine, the combination of two revoluble crimping-heads eonnccted to revolve in opposite directions, one of said heads being constructed to reciprocate in its bearings, substantially as described.

2. In a can-crimping machine, a crimpinghead supporting crimping-wheels provided with springs inclosed in the head for regulating the pressure of the wheels upon the can, substantially as described.

3. In acan-crimping machine, a crimping- 5 head having crimping-wheels supported in elongated bearings, in combination with a spring and a screw-plug for adjusting the substan tially as deported in radial arms on the head and projecting through the Walls into said recess, in combination with a tension device inclosed in each of said arms for regulating the pressure of the Wheels upon the can, substantially as described.

In testimony whereof I my signature in 20 presence of two Witnesses. 1
